I am submitting this complaint to report an unexpected transmission shift event that occurred while operating my 2025 Toyota Prius at highway speed which created an immediate and obvious safety risk. The event occurred on XXX. While driving my Prius at approximately 75mph on Interstate [XXX], I reached toward the center console area to retrieve my sunglasses. I did not intentionally move the shifter, but the transmission suddenly shifted from Drive to Neutral. After moving from Drive to Neutral, the accelerator no longer provided propulsion. At the time, my vehicle was traveling downhill and was being followed by an eighteen-wheel tractor trailer. The truck driver behind me had no way of knowing that my vehicle had unexpectedly lost the ability to accelerate. To avoid being struck from behind, I steered left into a paved median area, applied the brakes, and was able to shift back to Drive and merge into the traffic flow. Had a paved escape area not been available, it seems inevitable that our chances of being in a fatal collision with the vehicle behind us would be quite high. My concern is that a normal driver movement (reaching for an item near the center console while driving) may inadvertently have caused the transmission to enter Neutral at highway speed resulting in the possibility of serious harm or fatality. I believe this presents an unacceptable safety hazard and warrants investigation. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The small battery located in the back of the car has a serious problem. I have been stranded over four times now. The battery loses it charge or isn't being fully charged up. When I go to get in the car. The interior lights flash and it will not go into ready mode to allow the vehicle to be driven. I have been stranded four times. I resorted to have a jumper pack in the back of the car, but since the rear deck is powered. This last time I couldn't get it to open to use it. I have already had the battery replaced by Toyota under warranty. But I believe that the hybrid system is not fully charging the small battery up. This could be a serious problem if Putin the county, state or in a bad neighborhood.

I started hearing a scratching/rubbing noise from the brake, and feeling the scratching/rubbing through the brake pedal, making it difficult to push down. I almost crashed in the ally into my garage, but the emergency braking took over and stopped the car very suddenly, snapping my neck a bit, and it is still sore as of me writing this report. Since then brake pedal makes scratching/dry rubbing noise with heavy rubbing and grabbing feel through pedal. It only happens at 20mph or below during quick stops (not smooth stop, press pedal quickly), at 15-25% pedal position. When holding pedal at that position while moving, rubbing/grabbing through the pedal feels rhythmic like it's related to wheel rotation. If car is creeping in Neutral or Drive (no gas pedal pressed), and you lightly press the pedal, you can hear and feel like something is grabbing/releasing/grabbing/releasing. Sometimes it the brake pedal resists and there is a very loud rubbing or grinding noise, and I have to press the pedal very hard. This can also be replicated when the car in in Park. Lightly pressing on the brake pedal causes the braking pump to make a whirring sound to build pressure (this is normal), but at the end there is a scratching sound and grinding feeling in the pedal. I took it to the dealer 3 days after purchasing it on June 25th, 2025 and the assistant service manager reproduced the issue in front of me, and thought it was the brake actuator going bad or something with ABS. However, the master tech at the dealer just drove it around, DID NOT CHECK ANY COMPONENTS except the thickness of the brake pads, and declared everything fine. I fear for my safety in this car. If I am involved in an accident, it will be because the braking system failed in this car and the dealer refused to fix it.

These tires were purchased brand new and installed at Pep Boys on March 24th. By the 15th of this month—less than a month later—one of the tires had developed a bulge on its sidewall.bubbling on the tire sidewall . However, neither the manufacturer (Toyo) nor the retailer (Pep Boys) has been willing to take responsibility for the issue, refusing to process a return, issue a refund, or address the quality defect. I have clear photographic evidence demonstrating that this is undeniably a product quality issue!
